GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 399,703, dated March 19, 1889.

Application filed May Z2, 1888. Serial No. 274,654- (No medal.)

T0 all whom it may concern:

Be it known that I, JOHN F. SEIBERLING, of Akron, county of Summit, and State of Ohio, have invented a new and useful Improvement in Grain-Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to the means for compressing the grain to form the bundle and for 'tripping or setting the binder mechanism in motion to bind the grain; and it eonsists'in certain details of construction and arrangement of parts, hereinafter fully described and claimed.

In the accompanying` drawings, Figure l represents in rear elevation so much of a harvesting-machine as is necessary to show my improvement. Fig. 2 is a plan view of the camlever. Fig. 3 is a vertical section through the needle, needle-cam, cam-lever, switch, and compressor-arm. Fig. 4 is a side and an end view of the double switch detached. Fig. 5 is a rear elevation showing the position the needle, cam-lever, ne., assume in discharging the bundle. Fig. 6 is a plan view of the needle, packing, and compressing mechanism, the binder-table being broken away to show said parts. Fig. 7 is a rear elevation of the binderframe, table, and packers. Fig. 8 is a side elevation of the swiveling yoke connecting the compressor with the cam-lever. Figs. 9 and lO are detail plan and Jfront elevations, enlarged, showing the connections between the crank-arm on the needle-shaft and its actuating and tripping devices; and Fig. ll is afront elevation showing a modification in the construction of the connecting-rod between the needle shaft and its actuating crank-wheel and inthe arrangement of the cam acting on said rod.

The machine to which my improvements are shown applied is of the class known as an elevated binder, and the binder-frame consists of a longitudinal tubular rod or bar, A, the needle-shaft D, and sleeve B', in which said shaft is j ournaled, and connecting transverse bars O O. The rod or bar A is journaled in the outer ends of brackets a, secured to the outer uprights of the elevatorframe near their upper ends, and the lower end of the binder-frame is upheld by inclined standards a', secured at theirV lower ends to the machine-frame, and provided at their upper ends with halt-sleeves, in which the needle-shaft and its sleeve rest, and which permit said end of the binder-frame to be raised and folded over against the elevator for transportation. v

The sleeve B referred to is an arm of the binder-gear standard B, which is of the wellknown U shape, and in its other arm carries the knetter-actuating shaft, and from which the knetter' breast-plate and knetter mechanism are suspended under any usual or preferred arrangement. The sleeve B is provided on its lower side with laterally-projecting ears b t', to which the outer ends of the bars O C are bolted. The needle-shaftD extends beyond the sleeve D and the needle D', which it carries, and supports a flanged sleeve, B3, having a laterally-projecting lug, h2, to which the outer end of the binder-frame bar C2 is bolted. The sleeve B3 has an outwardly-proj ecting flange or rib, b3, on its lower side, to which a bar, O3, is bolted, and which extends rearwardly, forming a support for the outer edge of the binder-table at its rear end. The forward end of rib b3 is extended outward, forming an arm, h4, having a forwardlyprojecting pin or spur, h5, on its outer end, forming a iXed pivot, on which the upper end of one of the swinging packer-links is pivoted. A similar arm, h, on the rear end of the sleeve B', provided with a rearwardlyprojecting spur, forms a like support for the other packer-link, as shown in Fig. 6.

The needle D is fast on and vibrates with shaft D, and has on its heel end a cam, D2. (Shown in rear elevation in Figs. l and 5 and in vertical section in Fig. 3.) The cam has1 a thin vertical wall or web, CZ, forming its forward closed face or side, provided with a rearwardly-proj ecting peripheral flange, d', forming the outer wall of the cam proper. Within the open shell thus formed is located what I term a double switch, E, the form of which is shown in the detail views, Fig. Ll, and around which a friction-ro1ler,f, on a cam-lever, F, moves as the needle is vibrated, as will appear. This switch has a forwardly-projecting pivot, e, which is journaled in the wall (l,

IOO

and has a socket in its lower face, in which rests the upper end of a small spiral spring, e', which at its lower end rests on a ledge, cl2,l forming the upper wall of the cam-groove at that point. erted to rock the outer end, e2, of the switch up against the sleeve proper of the needle or upper wall, d3, of the cam; but this tension is overcome twice in the movement of the roller 1o f around the switch--iirst, in passing the end e2, as the needle rises to pass the band to the knotter in moving outward over the switch, from the position shown in Fig. l, and, sccondly, in rising on the inner side of the switch and passing the end e3 thereof from the position shown in Fig. 5- to that shown in Fig. l.

The cam-lever F is made in two parts, which permit the adjustment of the roller f to give it the proper working relation to the cam and switch. The upper part, F', has a sleeve on its upper end, through which the lever is journaled to vibrate on the bar A, and the part F is slotted at its upper end and connected by a through-bolt, f', with the part F', to permit its adjustment for the purpose explained. The heel end of the cam D2 has a projecting ledge or spur, d4, formed upon it, for a purpose that will appear.

G indicates the compressor, which is adjustably secured to the outer end of an arm, G', which is pivoted at its innerend in the heel of the needle above the cam D2, as shown at g, Fig. 3. The cam-lever F is bifurcated, or has a branch, f2, near its outer end, between which and the main body of the lever ayoke, H, is pivoted, said yoke being made in the rectangular form shown in Fig. S, and provided with trunnions h, which form the pivotal connection with the lever F. The ends of this yoke are perforated to receive a rod, 7i', surroundedwithin the yoke by a spiral spring, h2, and threaded near the upper end of the yoke to receive nuts 71,3 and h4, the first named for adjusting the tension of the spring h2, and the latter, 7L, for limiting the upward movement of the rod 7L.

' The nut h4, if preferred, may be placed on the lower end of the rod 7L, below the yoke H, as shown in dotted lines, Fig. '8. The upper en-d of the rod 7L has a hook or pin, h5, formed upon it, which enters a slot, g', formed in the complessor-supporting arm G. rlhe nut 7t4,as explained, limits the upward movement of the rod 7L' and the consequent length of the yoke and rod between the trunnions and the pin h5, and the slot g', in which the pin h5 rests, allows a slight downward movement of the compressor-arm G before it acts on the pin and rod to compress the spring 71,2.

The cam-lever F has an eye, f3, near its outer end, through which the lower end of a rod, l, passes, the upper end of said rod being pivoted to the arm G. Near the upper end of rod l is a nut, t', and between said nut and the lever F the rod l is surrounded by a spiral spring, t', the tension of which is regulated by the adjustment ot' the nut t, and is The tension of spring e' is ex-l exerted to uphold the compressor against the pressure of the grain.

The arm G is provided with a set screw or bolt, g2, the pendent head or end of which rests on the ledge or spur d* on the cam or heel extension of the needle, said ledge forming by this arrangement a rigid support for or connection of the compressor-arm with the needle in such manner that the first downward movement of the arm G' permitted by the slot g' before it acts on the cam-lever, and caused by the pressure of the grain on the compressor, causes said arm, acting through the set-screw g2 and ledge di, to rock the needleshaft slightly in its bearings for setting the binder mechanism in motion, as will appear.

The forward end of the needle-shaft D, or the end opposite that which carries the needle, has a crank-arm, D3, fast on it, from which a connecting-rod, J, extends to a crank-pin, k, on the gear-wheel K on the knotter-actuating shaft for actuating the needle shaft in the usual manner. The arm l)3 has a trip-arm, D4, fast upon it, the outer upper end of which reaches within the path of an arm, L, formed on a pawl, l, pivoted to a pinion, L', on a driving-shaft, L2, to engage a cross-head, L4, for actuating the pinion L', and thence, through the usual train of gears, the gear-wheel K on the knotter-actuating shaft when said pawl is not held disengaged from shaft L2, in a manner well understood.

To allow the slight rocking movement of the needle-shaft above referred to, for throwing the arm D4 up to release the pawl-arm L and throw the bindermechanism into action, it is necessary that the connecting-rod J shall yield slightly endwise. To permit this it is made in two parts, viz: the rod J proper and a yoke, J', on its upper end in which the rod J can move slightly endwise, and which at its upper end is connected to the crank-pin k.

The lower end of the yoke J is perforated to receive the end of rod J, and theupper end of the latter, within the yoke, is screw-threaded to receive an elongated sleeve-nut, M, which, when the connecting-rod is drawn to its greatest length` abuts against the lower end wall of the yoke, as shown in Fig. 9. A spring, j, surrounds the rod J between the yoke J and a nut, j, adjustable on a threaded portion,j2, of the rod for regulating the tens-ion of the spring, which is exerted to hold the parts in the position described. The spring j yields under the rocking movement of the needleshaft described, and allows the rod to slide in the yoke, into the position shown in Fig. l0, sufficient to allow the arm D4 to be rocked up out of engagement with the pawl-arm and so to throw the binder-gearing into action.

The upper end of the sleeve-nut M is drawn down or reduced in diameter, and is screwthreaded internally to receive a set-screw, m, provided with a jam-nut, m2, for holding the screw at any desired adjustment. The head m' of the screw lies within the path of a cam, N', formed on a washer, N, fastened bya key IOO IIO

or pin, n, to the outer end of the crank-pin 7o, and which acts on the set-screw m to force the connecting-rod J outward just before the wheel K completes its revolution, and causing the arm D4 to engage the pawlarm L if from any cause the spring j should fail to act for that purpose.

In Fig. llthe yoke is screwed on the rod J, and is adapted to slide on a crank-box, k', on the crank-pin k, and the spring j is arranged within the yoke between the crank-box k and an adjiistingnut, k2. In this construction the upper end of the yoke has a pin or spur on it, which is acted upon by a cam, N, on the face of the wheel K for forcing the pitman out to its full length.

The shaft L2, carrying the pinion L and cross-head L4, serves also as the crank-shaft, actuating the packers, and constitutes the iirst or main binder gearshaft.

The operation of the trip mechanism will be readily understood from the foregoing description.

The pressure of the grain against the compressor causes the depression of the compressor-arm, and the latter acts to rock the needleshaft sufficiently to rock the arm D4 up out of engagement with the pawl-arm L, thereby throwing the pinion L into engagement with its shaft and setting the binderactuating gearing in motion for binding the grain, after which the pressure on the compressor being removed, and the parts being returned to their former position, the arm D4 again engages the arm L and throws the pinion out of engagement with its shaft until the pressure of the grain on the compressor causes the operation to be again repeated.

The folding' leaf or hinged extension Q of the binder-table Q, 'which acts as a cut-off to check loose straw and is in common use, in my invention is connected through an arm, q, and link q with the outer swinging end of the camlever F. As the latter is depressed by the passage of the roller f under the switch E in the backward and downward movement of the needle, it serves to` withdraw the compressor out 0f the way of the bundle and to depress the leaf Q to the plane of the table Q, as shown in Fig. 5, to permit the discharge of the bundle in the usual well-known manner.

Having now described my invention, I claim as newl. The combination, with the needle and its shaft, of the cam rigidly secured thereto, the cam-lever pivoted on the frame, the yoke pivoted thereto, and the compressor connected to and supported by said yoke and also piv oted to the needle, substantially as described.

2. The combination of the needle-shaft, the

needle secured to said shaft, the cam secured to the heel end of the needle, the pivoted and adjustable cam-lever F, hinged at its upper end at or near the upper side of the binderframe and supported at its lower end and actuated by a cam-roller on said lever engaging the cam on the needle, the compressor, and the pivoted and yielding connection between the cam-lever and compressor, substantially as described.

3. The combination of the needle-shaft, the needle secured to said shaft, the cam on the needle, the compressor-arm hinged to the needle below the shaft, the spur on the needle vsupporting the compressor in position to receive the grain, the compressor connected to said compressor-arm, the cam-lever, the hinged connection between the cam-lever and compressor-arm, permitting said arm to yield, the supportingspring i', and the spring-rod I, hinged to the compressor-arm and connected with the cam-lever F, in the manner substantially as described.

a. The combination of the yoke H, the spring h2 in said yoke, the rod h', provided with the hook or pin engaging the compressor arm, the cam-lever F, hinged to the yoke, the compressor-arm G', and the compressor G, substantially as described.

5.

6. The combination, with the needle, the cam rigidly secured thereto, and the co1npressor, of the cam-lever carrying the camroller and made adjustable in length to preserve the cam-roller in proper relation to the cam, substantially as described.

7. The combination, with the needle, the adjustable compressor, and the compressor-arm connected with said n eedle, of the pivoted camlever F, the double switch E, and its spring e', the yoke H, and connections interposed between said lever F and the compressor, and the cam-roller f on the cam-lever F, substan tially as described.

In testimony whereof I have hereunto set p, my hand this 19th day of May, A. D. 1888.
